User manual - SR150 2-CHANNEL UNIVERSAL POWER AMPLIFIER | P 6
AMPLIFIER CONTROLS
On the front plate of the GOLDMUND SR150 amplifier you will find only one switch:
The POWER key, used to power the amp on and one power Led.
When turned ON the 2 channels are immediately connected and the front panel POWER Led
lights up. If you use the digital input, the lock of the digital input will indicate this by changing
the Led from green to yellow.
The amp may be powered off by turning off the POWER switch at any time. The Led will fade
very slowly, indicating discharge of the filter capacitors. The speakers will be disconnected
after a few seconds.
It is absolutely normal that a slight sound is heard from the speakers when the amplifiers
are turned ON or OFF. The SR150 is self-protected and the sound heard is corresponding to
the charging and discharging of the capacitors.
On the back panel, there is a 5 Switch set which allows adjusting the D/A Phase and
Gain for the digital input.
Each Switch has 2 positions : ON (high) and OFF (low)
Phase adjustment:
Switch 1 (rightmost) ON: 180 OFF: 0
Left Gain - 6dB: Switch 2: ON Switch 3: ON
0dB: Switch 2: OFF Switch 3: ON
